how to map classes in hibernate using the class attribute? - java

I have a problem in my maven project
click the links below to see it
I added this to my hibernate.cfg but didn't work
<mapping package="com.redpass.entities"/>
<mapping class="com.redpass.entities.MyReference"/>
console error
Project Explorer
hibernate.cfg.xml
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost:3306/avocatbd</property>
<property name="connection.username">root</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- <mapping package="com.redpass.entities"/>
<mapping class="com.redpass.entities.MyReference"/> -->
</session-factory>
</hibernate-configuration>

I should add this:
configuration.configure("hibernate.cfg.xml");
return configuration
.buildSessionFactory(new StandardServiceRegistryBuilder()
.applySettings(configuration.getProperties())
.build());
to my HibernateUtil Class to tell that we want to configure using the hibernate.cfg.xml file and map the classes like this:
<mapping class="com.redpass.entities.Partie"/>
<mapping class="com.redpass.entities.Societe"/>

Source button missing from hibernate configuration XML file in eclipse

When I created a hibernate Configuration file, eclipse is not able to display the source code as there is no source button at the bottom of the page. I can able to navigate between Session Factory and Security whereas Source button is missing. How can fix this issue? I have attached the picture below for reference.
Hibernate Configuration XML File
make your own one and add the below:
fileName is: hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/Book</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password"></property>
<property name="hibernate.connection.pool_size">1</property>
<property name="hibernate.current_session_context_class">thread</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<mapping resource="book.hbm.xml" />
</session-factory>
</hibernate-configuration>

I read that i should change the "Doctype" and i did from other answers i have found, yet this error occurs:
Unable to perform unmarshalling at line number 8 and column 63 in RESOURCE hibernate.cfg.xml. Message: cvc-elt.1: Cannot find the declaration of element 'hibernate-configuration'.
Your dtd url is false ... seems like hibernate-configuration-5.0.dtd doesn't exist ... use this :
http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd
change the whole header :
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-5.0.dtd">
<hibernate-configuration
xmlns="http://www.hibernate.org/xsd/hibernate-configuration"
xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configuration hibernate-configuration-4.0.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
TO
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
Try to add this header block. It works for me and also check parse error in your XML file.
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
Here i am posting some sample xml file may be it will help you.

Hibernate.cfg.xml not found after deploy the web app to heroku

After deploying a web application with maven to heroku cloud, I get log error:
app[web.1]: org.hibernate.HibernateException: hibernate.cfg.xml not found.
The web application running locally correctly, but on the cloud not.
This is my hibernate.cfg.xml:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">
com.mysql.jdbc.Driver
</property>
<property name="hibernate.connection.url">
jdbc:mysql://localhost:3306/todoitemsdb
</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">root</property>
<property name="show_sql">true</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<!-- Mapping files -->
<mapping class="il.ac.hit.model.User" resource="todoitems.xml"/>
<mapping class="il.ac.hit.model.ToDoItem" resource="users.xml"/>
</session-factory>
</hibernate-configuration>
What can I do?
Make sure that the hibernate.cfg.xml is bundled into your jar like this:
your-app.jar\hibernate.cfg.xml
That's where Hibernate tries to locate the configuration file.
I had my hibernate.cfg.xml under resources under a folder config
Changing the below line
cfg.configure("./config/hibernate.cfg.xml");
to
cfg.configure("config/hibernate.cfg.xml");
worked.

Hibernate, Could not parse configuration

The end tag for <hibernate-configuration> is missing:
</hibernate-configuration>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver </property>
Your opening tag not match the ending tag.
